Forum rulesYou're welcome to trade Acorn-related stuff with other forum members here - the rule of thumb to follow when trading, is that items or services offered should be of interest to our Acorn community. Do NOT use multiple accounts - please trade with your regular (and only) forum account. If you're giving items away, please make it clear if you would be unhappy with the recipient selling on some or all of the items. Similarly, please ensure that the giver is comfortable with you re-selling items you have accepted as a gift. We cannot be held responsible for what happens in these trading forums or for deals done via PM. This must be done at your own risk. If you aren't comfortable with this - make the trade via an alternative site which can apply safeguards of their own. Be sensible - if someone approaches you to trade via PM who is not posting in the public forums, this may be a sign that they are not entirely what they seem. Please report it to the moderators if you receive an unsolicited message from anyone suspicious, so that it can be investigated and hopefully stop anyone being taken advantage of.

I've made another batch of VideoNuLA boards. For anyone who has not heard of it yet, it replaces the original video ULA IC in the Beeb, Master, B+ or Compact to improve the graphics capabilities. It provides an analogue palette of 4096 colours, gives 16 proper colours in modes 2, adds new attribute modes and hardware support for smooth horizontal scrolling.

I'd like one! i can't PM you (it seems i've not enough posts to use private message ) I need shipping to Italy, hoping the cost will be around 5 pounds... please write you to me by PM for confirming availability, costs and payments modeThank you and again my compliments for your project!

The found the Instructions and photo in the pdf confusing as they didn't show the address line attachment to IC3 clearly (In fact the picture in the pdf showed what looked like a small chip - but in fact it was one of the largest - and you could have named it as the 6522 for confirmation...)Anyway I wired it all up and held my breath and then plugged it in and power it up - and it worked!

Hi RobI like your new hardware, but I prefer a portable (external) VNuLA for use for all of my BBCs.I use already portable Matchbox Co and DataCentre for all of my BBCs and I can exchange the hardware between them.I don't know if will be possible a portable version to the future.

The same board works in all of the models (B, B+, Master & Compact) and I often swap the boards between machines when I'm testing them.

It's also possible that it'll work on the end of a ribbon cable - I keep meaning to try this out but haven't got around to making up the cable yet.

Unfortunately though, there isn't an existing socket on the Beeb that it could plug into as the required signals aren't brought out to any of the existing connectors. So, even if it does work, it would mean having a ribbon cable running from inside the machine to the outside world (a bit like the Master AIV SCSI cable).

If you wanted to swap the board between machines, you'd need a ribbon cable coming out of each machine or would be opening them up to swap the cable over (in which case you might as well just swap the board over).
